摘要
以《现代操作系统》为例,在智能问答系统中,综合考虑问句的词和语义等多方面特征,并对编辑距离法进行改进,设计了一种新的组合式问句相似度计算方法。实验结果表明,该算法取得了良好的效果,可以有效地提高问答系统的性能。
The domain knowledge of Modern Operating Systems course was cited as a research instance. Considering word features and semantic features of questions, a new assorted method of question similarity algorithm based on improved edit distance algo- rithm was presented to increase the accuracy of finding similar questions. Experimental results showed that the assorted method a- chieved good results, and the performance of question answering system was improved.
